>>...you have to rely on some authority outside the Bible to confirm that what we read is Divinely inspired.<<
I agree. However, it is easy to cross a line. I trust NO man explicitly. I may agree with something the Pope says, or the president of the LDS or even Jim Jones. But I reserve the right, via prayer and a relationship with my personal Savior and Lord, to throw out anything I believe contradicts who the Bible says He is.
It is one reason I very much agree with this guy, and it is an “extra-biblical” source that is INTERPRETING scripture: http://www.freerepublic.com/focus/f-religion/2240648/posts
Don’t tell me you don’t belive in Hell!!!
